Then when i close it, it slowly moves the arm all the way back the other way. if i keep opening and closing it, this will continue. What could be the culprit of this? | | | | | Joined: Oct 2004 Posts: 1,780 Master Gabster | | Master Gabster Joined: Oct 2004 Posts: 1,780 | I am purely guessing, there is a fabric, maybe leather inside. Could this be dry? I remember siphoning 3 and 1 oil into the motor to make it work. That was 40 years ago. You manually manipulate the motor going back and forth. I think I used a rubber hose and sucked up the oil into the diaphragm. I hope someone else knows how to do it, I am sure mine is going to need repair too | | | | | Joined: Jan 2009 Posts: 1,644 Shop Shark | | Shop Shark Joined: Jan 2009 Posts: 1,644 | I have a rebuild of a wiper motor on my photo bucket,also if you're glass was dry they don't work so good ,I spray water on the glass to check.

If not, you might want to digest the information. Few vacuum wiper problems are new around here- always seems to be the same things since there aren't many parts in the assembly... Bill | | | | | Joined: Mar 2007 Posts: 4,215 Moderator | | Moderator Joined: Mar 2007 Posts: 4,215 | I was determined to get my vacuum wiper going too, I even bought a NOS wiper motor, also a 1953. It did exactly what you describe so I finally gave up and bought the electric motor. End of problems. | | | | | Joined: Jan 2010 Posts: 60 New Guy | | New Guy Joined: Jan 2010 Posts: 60 | This refers to a 48 passengers car but perhaps your wiper unit is similar.
Last month I also dismantled cleaned and lubricated the vacuum motor.With reinstalling it it behaved the same as yours.
After closer examination I found out that one of the rubber hoses was too old so it should not sit properly resulting in a vacuum leak.I relapsed all hoses with new ones and now it works perfect.

Tried 3 that claimed to be functional on 6v. Sent 'em all back. Some wouldn't even fit! My vacuum motor went to Chevs of the 40's for rebuild, and came back good as new. | | | | | Joined: Jun 2005 Posts: 422 Shop Shark | | Shop Shark Joined: Jun 2005 Posts: 422 | This guy does a great job on these vacuum motors...
